Abstract: The imaging lens consists of, in order from the object side, a positive first lens group that moves to the object side during focusing from a long distance to a short distance, and a second lens group that does not move during focusing. The first lens group has a first-B sub-lens group. The first-B sub-lens group consists of, in order from the object side, a positive b1 lens, a negative b2 lens concave toward the image side, an aperture stop, a negative b3 lens concave toward the object side, and a positive b4 lens. The second lens group consists of, in order from the object side, a negative lens, a positive lens, and a negative lens. Predetermined conditional expressions are satisfied.

Abstract: The imaging lens includes at least one positive lens that satisfies predetermined conditional expressions (1) to (3) indicating conditions in which dispersion is relatively low and refractive index is high while having a negative rate of change of the refractive index. In a case where a lens that satisfies a conditional expression (4) meaning a low dispersion material is included, the lens that satisfies the conditional expression (4) satisfies a predetermined conditional expression (5).

Abstract: The imaging lens includes, in order from the object side, a first lens group that remains stationary during focusing; a diaphragm; and a positive second lens group that moves to the object side during focusing from a long range to a close range. The second lens group includes a positive Z lens that is formed continuously in order from a most image side, a negative Y lens that has an absolute value of a radius of curvature of an object side surface smaller than an absolute value of a radius of curvature of an image side surface, a positive X lens, and a negative W lens that has an absolute value of a radius of curvature of an image side surface smaller than that of an object side surface. The imaging lens satisfies a conditional expression about of the radii of curvature of the X lens and the W lens.
